Without seeing the specific log messages I do not know exactly what
is happening. You should also let me know which version of zxid you
are using (latest is 0.32).

In your scenario you presumably want the EPR of the WSP. The WSC can
find this out in two ways:
1. it could have been passed as "bootstrap"
attribute in the SAML SSO assertion; or
2. it can be discovered from the discovery service, however to discover
the IdP must have passed a discovery bootstrap attribute containing
the EPR of the discovery service and the Discovery Service
must be running.
So I suspect the Lasso IdP is not passing a bootstrap attribute
of either variant.
While ZXID fully implements discovery client, I do ot yet have
Discovery Server implmentation, though this is being worked on
as part of zxid IdP implemetation. Only open source discovery
service implementation I am aware of is by Conor Cahill
but his implmentation is not very well integrated to any SSO IdP.
Other alternative, as you say, is to use a commercial discovery
server implmentation. For example symlabs.com offers free
What is your timeline for getting the Discovery in place?
